Hi All

Recently acquired a Rolex 6303 with a Cal 645.
The barrel cover was loose from poor workmanship. I bought a similar Cal 600 cover which looks correct but still doesnt hold.
Is there a way to stake a barrel closed? I tried tapping the rim in a little but may have damaged a tooth. Please help!!!!!!!


If anyone has a source on Cal 645 parts I would be indebted. Willing to pay good money for a part to get this flipping watch back together (3 months on my bench so far).

If you own a lathe then you could spread some of the material (preferably in a vice rather than punching) and then turn it concentric if need be. 

Has the barrel or barrel rebate been stretched or worn? It can happen when a spring suddenly breaks. On larger clocks this can even shatter the barrel wall (been there).

I don't have a lathe sadly.
The barrel cover appears flat as I ordered a replacement which was either NOS or very good condition. The original was flimsy and buggered.
It had been worked on by Indonesian watchmakers who are not to a very high standard. The watchmaker who sold the watch is based next to a rice filled.

He did bizarelly have a Jean Claude Dato Compax rolex in pieces on his bench!!!!!!!!!

Is a broken barrel tooth something that can be repaired? should I write off the barrel. Will it just slip past that tooth if I file it down?

Check if the barrel wall is cracked.

Damaged tooth on barrel.. while the watch may work, there will be a shock to the train when the barrel reaches the broken tooth and releases. Not good for the train.

Your best bet would be to look for a new barrel with lid.

Good luck!

      Argh. Breaking pallet pivots

      By Nucejoe · Posted

      If a runner, I usually let the movement run in naphta for a minute, some movements need a bit of encouragement to run in liquids, so a quick dip of the movement in naphta then remove and encourage the oscilator with puffer, repeat several soaks.  Or if you don't want to soak or dip the movement in cleaning solution ,   keep putting naphta on jewel holes as the movement runs on desk. A pre-clean of some sort is helps.  Avoid lifting out the fork with tweezers.  Try blowing fork pivot out  with strong puff of air from jewels holes back side. Good luck .

      60! Wow, that's a lot. Can't say I understand the problem because disassembly is usually quite uneventful, except for springs launching into space. Most people break pivots during assembly. I use a homemade brass pry tool to loosen parts. It's just a short length of hard brass wire sharpened to a chisel point. Don't pry at just one point and crowbar it out. Pry at the notch and when a crack opens up, slip the pry tool in and loosen it at a few more points until the bridge is free.

      Argh. Breaking pallet pivots

      By WpgRob · Posted

      Beginner here. Of about 60 watches I’ve serviced and repaired, I’ve broken a pallet pivot on three, always during disassembly, and usually when the old oil has transformed to glue. Each watch was Swiss, in case that makes a difference. Here’s what happened in each case: - unscrewed the pallet bridge or cock - gently inserted a screwdriver in the  slot under the pallet bridge or cock - gently but firmly rotated the screwdriver, avoiding a forwards force on the screwdriver. If alignment pins stick, the cam action is alternated back and forth between back corners of the plate. - heard a small but horrible click. Is there a special tool or technique for safely lifting the pallet bridge? Should everything be soaked in naphtha before beginning disassembly if there’s any sign of old oil gluing parts together? Thanks! Rob

      Full plate watch, Suitable tool for adjusting & testing pallet stones?

      You shared this test with me a few months back on a Hamilton project and so I had checked this watch to find the pins were still equally spaced. Their screw slots were undamaged and very tight hard to move so maybe no one has messed with them before. I can't work on it much today but I did measure the fork slot again and it seems like 0.44 is the right size. I measure the jewel that had been installed at just 0.42. would an undersized too narrow impulse jewel impact the impulse drastically? I ask because I have had it at a state where flipping the fork manually with a tool would unlock some of the time, but the balance was never capable of unlocking.

      Help with repairing a quartz clock

      By HectorLooi · Posted

      This was what I was afraid of. The movement is not one of the generic black square modules. Remove the movement from the clock and try prying it open very carefully, without breaking the plastic tabs. The plastic might be brittle from age. Clean the wheels and check the battery contacts for corrosion. Check the PCB for bad solder joints. Take plenty of photos along the way.
